The ADP163AUJZ-R7 is part of the Analog Devices Power by Linear™ family. It is a low quiescent current, low input voltage 500mA LDO (Low Dropout) Linear Regulator, most suitable for battery powered, portable applications. The ADP163AUJZ-R7 features a 0.2Ω internal PMOS power switch, allowing for efficient regulation of input voltages from 0.9V to 3.6V with a 0.8V to 3.3V adjustable output voltage range. The device also features a 1.2MHz switching frequency, a wide operating temperature range, and over-temperature and over-voltage protection.

The ADP163AUJZ-R7Linear Regulator is typically used in portable consumer electronic products like cell phones, smartphones, tablets and other handheld devices which require low voltage and low current loads. The device offers superior power efficiency, exceptional power accuracy and low noise compared to other linear regulators, thus enabling longer battery life in portable consumer applications. Additionally, it can be used in always-on power-down applications to keep the system running.

The ADP163AUJZ-R7 is based on a linear regulator design and works by taking the difference between the input voltage and the desired output voltage level, then using a PMOS pass transistor and an error amplifier to step down the voltage. The voltage is then regulated via feedback control, where a comparator works to maintain a constant output voltage. In order to keep the output voltage constant, the output voltage is compared to a reference voltage from a band gap reference circuit. This voltage is then applied to the error amplifier, which adjusts the gate voltage of the PMOS to maintain the output voltage at the set value.

The main features of the ADP163AUJZ-R7 include: a low quiescent current of 9µA, a low dropout voltage of 250mV, a wide input voltage range from 0.9V to 3.6V, adjustable output voltage range from 0.8V to 3.3V, an excellent load regulation of 0.1% over load and line, over-temperature protection, and over-voltage protection. With its ability to maintain stable outputs with a low quiescent current and an adjustable output voltage range, the ADP163AUJZ-R7 is a versatile device suitable for a variety of power supply applications.

The ADP163AUJZ-R7 is part of the Power by Linear family and is an ideal choice for portable consumer electronics applications. It is a versatile device that offers low quiescent current, low dropout voltage, wide input voltage range, adjustable output voltage range and over-temperature and over-voltage protection.
